Indicates if the storage instance is active and ready to perform updates/writes.

Blocks until all earlier tasks have completed and then prevents further tasks from being run.

Current state

Check whether we're closing. Susceptible to race conditions; unless you're using using this as a flag to the retry lib or you really know what you're doing, prefer performUnlessClosing and friends.

track running futures on shutdown

set to true to get detailed information about all futures that did not complete during shutdown. if set to false, we don't do anything.

Returns database specific limit [offset] clause. Safe to use in a select slick query with #$... interpolation

Name of the health element. Used for logging.

Performs the task given by f unless a shutdown has been initiated. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosingF and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of f, because it will result in a deadlock.

Performs the EitherT[Future] given by etf unless a shutdown has been initiated, in which case the provided error is returned instead. Both etf and the error are lazy; etf is only evaluated if there is no shutdown, the error only if we're shutting down. The shutdown will only begin after etf completes, but other tasks may execute concurrently with etf, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingF). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of etf, because it will result in a deadlock.

Performs the Future given by f unless a shutdown has been initiated. The future is lazy and not evaluated during shutdown. The shutdown will only begin after f completes, but other tasks may execute concurrently with f, if started using this function, or one of the other variants (performUnlessClosing and performUnlessClosingEitherT). The tasks are assumed to take less than closingTimeout to complete.

DO NOT CALL this.close as part of f, because it will result in a deadlock.

Query and update in a single action.

Note that the action is not transactional by default, but can be made so via using queryAndUpdate(action.transactionally..withTransactionIsolation(Serializable), "name")

The action must be idempotent because it may be retried multiple times. Only the result of the last retry will be reported. If the action reports the number of rows changed, this number may be lower than actual number of affected rows because updates from earlier retries are not accounted.

Set the health state to Ok and if the previous state was unhealthy, log a message to inform about the resolution of the ongoing issue.

Register a task to run when shutdown is initiated.

You can use this for example to register tasks that cancel long-running computations, whose termination you can then wait for in "closeAsync".

Write-only action, possibly transactional

The action must be idempotent because it may be retried multiple times. Only the result of the last retry will be reported. If the action reports the number of rows changed, this number may be lower than actual number of affected rows because updates from earlier retries are not accounted.

Runs the given query transactionally with synchronous commit replication if the database provides the ability to configure synchronous commits per transaction.

Currently only Postgres supports this.
